CFD simulation of vortex-induced vibration of a vertical riser

Research output: Contribution to conferencePaper

Abstract

Three-dimensional fluid-structure interaction (FSI) simulations are conducted on a vertical riser with a length-to-diameter ratio L/D = 481.5. Important vortex-induced vibration (VIV) parameters including the amplitude responses, orbital trajectories, oscillation frequencies and vorticity contours are presented. The computational fluid dynamics (CFD) simulation results are in good agreement with published experimental data. The riser exhibits a dual-resonant response. Two different vortex shedding mode is observed, i.e., 2P and 2S modes. 2P mode is associated with the maximum transverse amplitude and 2S mode is observed elsewhere along the riser.
